[0004] The disadvantage of the above patent is that the plug and the jack are connected to the socket mainly through friction. On the one hand, the user needs to overcome a large friction to plug and unplug the plug, which is inconvenient to use. On the other hand, after long-term use, the above method can easily cause the plug and the jack to become less and less tight and loose, resulting in poor line contact. Summary of the Invention

[0005] The present invention aims to overcome the defect in the prior art that the fit between the plug and the socket is not tight enough, and provides a socket with a lock which can improve the tightness of the fit between the plug and the socket.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The lock is elastically connected to the inner core and provided with a spring and an action block. The spring is located on one side of the lock block and is located on the rotation plane of the lock block relative to the inner core. The lock block is elastically connected to the inner core through the spring. The other end of the lock block is provided with an insertion block, one end of the insertion block is fixedly connected to one side of the lock block, the other end of the insertion block passes through the side wall of the inner core and is located in one of the insertion slots, and the action block is fixedly connected to the other side corresponding to the lock block. The upper cover is provided with an arc side plate 1, one end of the arc side plate 1 is fixedly connected to the edge of the upper cover, and the other end of the arc side plate 1 drives the lock block to rotate by contacting with the action block. The plug used in conjunction with the present invention has a lock hole on one of the pins of the plug that matches the plug block; in the initial state, according to the principle of leverage, the spring acts on one end of the lock buckle, so that the plug block on the other end of the lock buckle is located in one of the plug slots, and at the same time, the action block contacts the end of one of the arc-shaped side plates; when the pin with the lock hole is inserted into the plug slot, the end of the plug block on the lock buckle located in the plug slot slides into the lock hole through the side of the pin under the action of the spring, so that the pin is locked. The present invention realizes the connection between the plug and the socket through the lock buckle, thereby achieving the purpose of improving the tightness of the fit between the plug and the socket. At the same time, when it is necessary to unplug the plug, the user only needs to rotate the inner core by a certain angle, so that the inner core drives the action block on the lock buckle to rotate synchronously, and the action block rotates relative to the end of the arc-shaped side plate one. Since the action block is always in contact with the end of the arc-shaped side plate one under the action of the spring, during the rotation of the inner core, as long as the end of the arc-shaped side plate one acts on the action block, the lock buckle rotates outward and drives the plug block out of the lock hole, the plug pin can be pulled out. After the plug pin is pulled out, the inner core is reset under the action of the spring. The whole process does not require overcoming a large friction force to realize the plugging and unplugging of the plug and the socket, which saves time and effort and is convenient and quick.

In the initial state, the action block contacts the end surface of the arc-shaped side panel 1; when it is necessary to unplug the plug, the user rotates the inner core to a certain angle, and the inner core drives the action block on the lock buckle to rotate synchronously to the end surface of the protruding plate 1 through the transition slope. During this process, under the influence of the resistance surface, the spring is gradually compressed, and the lock buckle gradually rotates toward the outside of the plug slot, eventually driving the plug block to completely disengage from the lock hole, making it easier for the user to unplug the plug more conveniently and quickly, and the operation is simple.

[0051] like Figure 16 As shown, a limit block 48 is provided on both sides of the open end of the U-shaped groove 19. The limit block 48 is L-shaped. One end of the limit block 48 is fixedly connected to the open end of the U-shaped groove 19 and forms a whole. The other ends of the two limit blocks 48 together constitute a limit groove matching the action block 6, and the action block 6 is located in the limit groove.

[0052] like Figure 1、 Figure 7 and Figure 11 The sockets in the three embodiments shown have the same structure of the inner core 1. The plug used in conjunction with the present invention has a lock hole on one of its pins that matches the plug block.

[0053] In the initial state, according to the lever principle, the spring 5 acts on one end of the lock 4, so that the plug 7 on the other end of the lock 4 is located in one of the insertion slots 3. At the same time, the action block 6 contacts the end surface of the arc-shaped side plate 8. When the pin with the lock hole is inserted into the insertion slot 3, When the plug is pulled out, the inner core 1 is reset under the action of the spring 5. The whole process can realize the plugging and unplugging of the plug and the socket without overcoming a large friction force, which is time-saving and labor-saving, and convenient and quick.

[0054] One side of the arc-shaped opening 25 is close to the convex plate 28, and the other side of the arc-shaped opening 25 is away from the convex plate 28. In the initial state, the side of the arc-shaped opening 25 away from the convex plate 28 and the convex plate 28 together form a restriction area, so that the convex parts on the limiting plate 26 and the stop bar 30 are both located in the restriction area, and the limiting plate 26 is in contact with the side of the arc-shaped opening 25 away from the convex plate 28. At the same time, the convex part of the stop bar 30 is located on the end surface of the arc-shaped side plate 27 and in contact with one side of the convex plate 28, so that the inner core 1 is well limited without external force and is not easy to rotate. When the plug needs to be unplugged, , the user needs to rotate the inner core 1 so that the limit plate 26 rotates toward the side of the arc-shaped opening 25 close to the second protruding plate 28. At the same time, since the stop bar 30 is overhead on the side wall of the back cover 12, the stop bar 30 has a certain elasticity, which makes it easy for the raised portion on the stop bar 30 to overcome the resistance and rotate to the other side of the second protruding plate 28. Therefore, the user will feel a certain resistance when rotating the inner core 1. When the resistance is eliminated, it means that the raised portion on the stop bar 30 has rotated to the other side of the second protruding plate 28. At this time, the plug 7 has completely disengaged from the lock hole, and the user only needs to unplug the plug. It has a good indication function to prevent misoperation.

[0055] like Figures 1 to 6In the first embodiment shown, a plurality of mounting ears 31 are provided on the edge of the upper cover 2. The mounting ears 31 are fixedly connected to the upper cover 2 and form an integral body. The mounting ears 31 are provided with mounting holes 32 to facilitate the installation and fixation of the socket.

[0056] like Figures 7 to 10 In the second embodiment shown, according to different usage scenarios, the inner core 1 is located in the cylinder 33 and is closed by the blind cover 34, so that the structure of the inner core 1 is not exposed to the outside, which provides good protection for the inner core 1; at the same time, the installation design of the blind cover 34 and the wiring block 35 is conducive to the installation and maintenance of the socket.

[0057] like Figures 11 to 15 In the third embodiment shown, this solution facilitates the installation of the socket within a wall. The socket is embedded within the wall, secured via a connecting piece 47, and electrically connected to an external grounding circuit. Multiple inner cores 1 can be provided within cavity 37 as needed. Furthermore, to facilitate the installation of the socket within the wall, the wiring slot 41 is designed so that the wires can be embedded within the wiring slot 41 when connected to the wiring bolts 42. This prevents damage to the wires from friction with the wall during installation or removal, thereby improving safety.

[0058] The embodiments of the present invention described above are merely illustrative. Those skilled in the art will appreciate that the present invention can be modified in various ways and implemented in other equivalent embodiments. Therefore, the present invention is not limited to the embodiments disclosed in the detailed description. The true scope of protection of the present invention is determined by the technical concepts defined in the accompanying claims, i.e., the scope of protection of the present invention includes the concepts defined in the accompanying summary of the invention and all modified embodiments, equivalent embodiments, and alternative embodiments within its scope.
